Can you enjoy a concert if you've never heard the songs?  

So last night hubby and I went to a Maroon 5 w/ Counting Crows concert. We had a blast and feel so lucky to have been able to see these 2 great bands live.
Counting Crows was the last act. Basically the only Counting Crows songs I know are the ones that are played on the radio.. and this is a band that likes to just flat out JAM. They would start a song, then half way through it, it would appear as if the singer, Adam Duritz, got side tracked and began singing a different song.. partially talking.. it's rather hard to explain. But then at the end of the song he'd go back to the original song he had been singing and finish it right. The only song they did beginning to end with no interruption was Mr. Jones... and half of the audience left after that. We stayed for a few songs after that, but we didn't know any of them, and he kept "jamming" in the middle of the songs, which seemed to make the songs last forever. I guess a lot of people like that sort of thing... but we ended up leaving before the end of the act. We weren't really enjoying the concert anymore when we didn't know any of the songs, plus we'd been there 4 hours already, so we were tired and worried about the kids.
I'm not complaining though... it was a great concert and I am so glad we went. I think it was an awesome experience to see such great bands live in concert.
My pictures are all very fuzzy because I was moving around and couldn't hold still, lol... but here's one I took of Counting Crows performing...
